laboratory test tubes science research
Prompt
Photorealistic close-up of a row of clear plastic laboratory test tubes standing upright in a black sample rack on a warm wooden bench, each tube sealed with a vivid red cap. The tubes are empty or nearly transparent, with only faint, intentionally unreadable gray markings and measurement lines catching the light. Composition is tightly framed at bench height, caps forming a strong horizontal band across the upper third, with repeating vertical glass-like cylinders creating rhythm and depth. Background is a softly blurred clinical interior in neutral gray and black, natural overhead lab lighting with gentle reflections, calm precise medical research mood, palette of red, clear acrylic, matte black, warm wood, and cool gray. Shot on 85mm macro lens, f/2.8, shallow depth of field.
